CARBURETER DEVICE.

Specification of Letters Patent.

Patented Feb. 24, 1920.

Application ined January 2, 1917. serial No. 140.061.

My invention relates to carburetci devices,A

and especially to devices which generally considered may be regarded as primers, that is devices adapted for use in connection with or as a part of a carbureter device and con Istructed to exercise some function or bring about some result in addition to the usual carbureter action.

The principal object of my invention is to piovde a simple. practical and eilicient primer or auxiliary mechanism adapted to exert a vheating effect upon the liquid fuel supplied to the combustion engine, so that in ,cold weather the liquid fuel may be heated as desired, but more especially at the time ot' staiting the engine.

A further object. is t arrapge for the ready control of this primer device, so that the heating etlect may be varied as desiied,

both as to amount and as to time of its apl plication.

A further object is to simplify the oonstruct-ion and reduce the cost of manufacture and make the device compact so as to avoid undesirable enlargement ofthe engine parts.

A further object is to arrange so that this primer mechanism may be used only at predetermined times` as for example when the engine starter is in use.

In the accoinpairving drawings Figure l is a perspective view of an internal.combustion engine, such for example. as is in use upon a. commercial type of automobile of the present day, together with a carburetor and a primer inechanisn'i involving my present invention;

Fig. 2 is a view partly in elevation .and partly in vertical section of such primer mechanism Fig. 3 is an end view of the same; an y Fig. 4 is a View of a detaill of construction.

Referring first. to Fig. 1, A represents an internal combustion engine arrangement,

such. for example as an automobile engine of the present eoiniiierc-ial type. A carburetor 2 is shown mounted on one side of this engine structure. through thi` medium of a pipe 2 which is the mixture intake pipe or conduit for the engine. and a mixing chamber 3' which-forms part of thil carburifter I. A4 liquid fuel supply pipe Je is shown con niected with the lower portion 5 of the carburetor l, which portion 5 is the usual Huid chamber of the carburetor. It will be understood that the carbiireter 5 is a commcri cial type of carbureter in connection with which my invention may be used. It will be understood, Aot' course. that the invention is not limited to use with any particular type of carbureter, but may be used with various kinds of the same.4

Referring to Figs. 2., 3 and 4, the auxiliary or primer mechanism involving my invention which is `shown in these figures coniprises preferably a tubulinl member 7 of substantially cylindrical form, haring a side extension or win r 8, preferably made integral therewith. his side member 8 has an aperture 9 and is adapted to be inserted between the engine intake pipeQ and the engine as shown in Fig. 1, so that the aperture 9 corresponds with the interior bore of said pipe Small apertures are also provided in the wing member 8, through which bolts 10 may be passed to bolt the styiliiticture firmly to the engine member A. The tubular mem bei* 7 is connected with a pipe 11 which extends from the lower end of said member to the fluid chalutier 5 of the carbuieter, whereby liquid fuel may pass .from said chamber 5 through the pipe or tube 11 and upwardly into the interioi-ofsaid niemibcr'. A chamber 12 is located at. the lower end portion of said member 7. said chamber being iii commiinioation with` the pipe 11 whereby fuel from the latter will paas into the chamber 12. A coil of wire 13 is also arranged within the chamber 12, one end of said coil havin a connection not shown) with the meta lic body part of the member, the other valve 16 whereby fuel coming upwardly through the chamber 12 passes into the chamber 17. An air inlet pi e 18 is arranged in one side of the mem er 7, affording communication between the outslde an' and the 'interu'icdiate chamboitl'l. Passages or ducts llt-19 extend laterally in the mem her 7 and wing it, affording eoimnuniration between the interior of the chamber for the valve 16 and the opening 9. whereby fuel and air passingr into the chamber 7 may when said valve 1.6 is open. pass through the ducts 19, into thc aperture 9, and thus into the bore or conduit formed by the pipe 2. The valve 16 has a centrallyr arran ed portion 2O of insulating material w iich insulators the connecting wire or rod 15. The coil 13 is also surroumled by an insulating member 21 of eylindrie form` said member 21 toi-ming the chamber 1;. 0n the upper end ot' the valve. 1u is located a metallic con tal-t or terminal 1-l and this cooperates with a contact spring' mounted above said con tart. and conveniently held in position by a. laterally` civ-udine' arm l on a hrailiet 25 which lis secured. as h v ,screws QG, to the upper poition ot the lwlmlar member T, (Fig. 3l, Thus it will he seen that the lon gitudiual movement ot' l'lu` valve 16 not only opens and closes the sido ports or passages 1f). but also maltese eonneetioi'i between the contacts and 23, and thereby makes and breaks a circuit connection with the coil 1?.

For effecting this longitudinal movement of the valve 16, Vl show as a convenient ar rangement a cam .28 carried by the upper end of said 'valve 1G and a ram groove Q9 formed by cam projections 30 and 3l on the bracket 25. so that the rotary movement oi said valve will eli'eet its longitudinal adjustment. A laterally projecting side arm 32 is shown connected with the upper end of the valve 1G, being' preferably made integral with the cam 2S. and a rod 34 is shown (Fig. l), connected with said arm 32 and extending from `the sameto some eonvenient position, as for example, to the dash board of the automobile, so that the longitudinal movlrment ot' said rod 34 lwill et feet a rotarymovement of said valve and thereby canse a longitudinal adjustment of the same.

twill` 'now he evident that the device may be put into operation by such al move-y ment of\the rod 34 as will enlise the valve 16 to move upviardly and thereby open the ports 19 and at `the same. time connect the coil 13 in circuit. byeleetiugr contact betwhen the terminals 22 and 23. "hen this is doneI the coil itl will be ei'iergized or heated so that liquid fuel rising in the pi )e 11 and passing: through the. chamber lZ will be heated and by passing through the chainber 17 and facts l!) and into the engine manifold will he supplied to the engine, eylof course are objectionable.

inders in a heated condition. At the seme time air will enter the passage 18 and will become mixed with the fuel in the chamber 17, and thus pass with it into the ducts 19 and engine cylinders, thus affording the engine a heated mixture. This movement of the liquid fuel uml air is caused by the suction or partial vacuum formed in the en rine manifold and pipe 2 by the operation o the engine. it `being seen that tiis will occur when the engine is started 'by external sources, as for example, by a hand crank or by an engine starter forming` part of the automobile equipment. Thus during the starting operation of the engine this heated mixture will be supplied to the cylinders, and this will prove very advantageous 'when the engine is cool, as duri-ng winter weather. At the same time more or less fuel will be supplied by the carhureter 3. the relative amount supplied by the priming mcchanism and the earhureter being varied aeeording to the extent to which the valve lli is opened` The extent to which the fuel may be heated by the coil 13 may be controlled by suitable control of the amount of current passing through said coil.

As a mattez' of further improvement I provide an arrangement h v which this priming mechanism may be used only when the starting' mechanism of the automobile is in use. This may be adopted or not as desired` but has the advantage that the heating coil 13 cannot he energized except when the startingl mechanism is running and conse- 100 fluently cannot be overheated or burned out at other times` either by accident or earelessness. This arrangement consists in providing circuit connections controllable by y the starting' mechanism, as for example, by 105 exte'ndin; l a circuit wire, 35 from the screw 3G connected with the spring Contact 23 to a terminal or contact 37 cooperating with a :ontact 38 and insulating stri i 39 on a rod 40 which is understood to be t 1e rod orcon 1.10 nection of the startingr mechanism, opelv ated to throwr said mechanism into and out of operation. Another contact 41 is shown cooperatingr with the Contact 38 and insula tion 39, and the connection 42 between said 115 contact 41 and a battery 43. Thus the actuation of the rod 40 either makes or breaks the circuit leading to the priming mechanismheating coil 13, so that when said circuit -is closed, said hea-ting coil may be einergizedebut when said circuit is open, sai'd heating coil may not b'e energized, and-con sequentlv cannot be heated, even thouiih the rod 34 be actuated so as to openfthe valve 16 and close the contacts 22 and 23.

The introduction of air thlough the inlet 18 is very advantageous inasmuch 'as it sprays or atomizes the fuel and so prevents the. fuel from having large globules, which ltfwill be understood that changes and Inralifications may be made without departinf: from the spirit of the in\eution.
